Answer:
B. It was passed to the individual by a gamete from the father.
Explanation:
<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.
Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.
Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
<h3><u>Answer;</u></h3>
The polysaccharide is <u><em>Hyaluronic acid</em></u>
<h3><u>Explanation;</u></h3>
- <u><em>Hyaluronic acid is a natural polysaccharide</em></u> which is in the class of glycosaminoglycans that is mostly found in <em><u>neural, connective and epithelial tissues in human body. </u></em>
- <em><u>Hyaluronic acid is made up repeating units of glucuronic acid and N-acetylglucosamine</u></em> that are<em><u> joined by alternating β- 1,4 and β- 1,3 glycosidic bonds. </u></em>
- It is a <em><u>linear polysaccharide and is the only glycosaminoglycan </u></em>that lacks sulfate atoms in its structure.
